What are the big differences that you have noticed among those exhaust tips? Did you have a second choice or are they all very similar?

Looked in the local auto stores, they did not anything that would fit the RAV4. The unit I purchased off of eBay looked decent, was reasonably priced and listed as fitting a 2013 RAV4. I also emailed the seller the dia of the exhaust pipe to make sure it was going to fit. It fits and is secured by an allan key lock nut combination.
